Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 465
IntroThe GeForce GTX 260 Core 216 has a core clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit memory bus, and uses a 65 nm design. It is made up of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.Compare those specs to the GeForce GTX 465, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 RAM runs at a speed of 802 MHz on this particular model. It features 352 SPUs along with 44 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 260 Core 216 should in theory be a little bit superior to the GeForce GTX 465 overall. (explain)
Texel RateThe GeForce GTX 260 Core 216 will be much (about 55%) more effective at AF than the GeForce GTX 465. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 465 is a better choice, but not by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
